Two invasive insect pests, emerald Ash Borer (EAB) and brown marmorated stink bug (BMSB) were found in new locations during March.
Despite this new infestation, EAB has still been confirmed in only four counties in Minnesota. In addition to Ramsey County, EAB has also been identified in Hennepin, Winona, and Houston Counties. You can use this MDA map to see where EAB has been confirmed in Minnesota. For more information on EAB, see the Extension emerald ash borer page.
So far, BMSB is not very common in Minnesota and all of the specimens of this insect have been discovered in homes during winter. The Duluth find is the furthest north this insect has been found in Minnesota. BMSB has been found primarily in the Twin Cities area (Anoka, Carver, Chisago, Dakota, Hennepin, Ramsey, Washington Counties) as well as in the southeast corner of the state (Winona County). For more information on BMSB, see the MDA fact sheet.
If you believe you have discovered an insect that is a brown marmorated stink bug or a spotted wing drosophila report it to the Minnesota Dept. of Agriculture at 888- 545-6684 or Arrest.The.Pest@state.mn.us.
